View Full Version : Another Shower Remodel Question

01-11-2017, 02:46 PM
Background: 1970's brick home on concrete slab. Standard tub and tile job in track home. Shower wall basically caved in at faucet handle.
Tore out everything down to studs. Replaced galvanized with PEX/Sharkbite to main header. Replaced some studs, adding some studs.
Replacing tub with walk in shower using hardie concrete board and Goof Proof Pre-pitch/Perfect-pitch system - probably throwing in a bit of waterproof paint for good measure.
My Question: How to I handle the huge hole in the slab surrounding the existing tub drain? Obviously not a problem when there was a steel tub there but since I'm going to be laying a mortar bed... now it's a problem.
My solution is to back fill with peagravel/sand mix - pack tight to an inch of foundation level - then mortar it in with the mud mix. (obviously after I've set the new drain.)
Are there any other suggestions? Problems with my solution?
Thanks in advance.

Welcome. Please replace that permanent signature line with a first name for us to use.

I'd first pull out the plastic liner, then fill the hole to the bottom of your concrete slab with a packable material, then fill to the top of the existing slab with a concrete mix leaving a void sufficient for attaching your drain or after installing your drain.

My opinion; worth price charged.

yeah, I've rethought the pea gravel part... t got stuck in my head due to a youtube video I watched... He also used expanding foam and I said, oh hell no..... I would mix and pack it with sand....then thought... why would you do that - just make it all sand....
Thanks - I just wanted to make sure I wasn't overlooking something stupid. The other showers I installed were wood floor construction.

I can't think of anything catchy to add to my signature!
So it's just:cheers: - Toni

I've gotten the shower pan poured including 40mil liner, hardieboard up, waterproofed with redguard, ledger boards set. Picked up my tile and the guy at the shop sold me this set: Crest Porcelanato.
Afar I'm poised to start,I'm concerned using this in shower floor and walls with ceramic tile.
Do? Don't?

A link to the product(?) in question would help, Toni? Not sure if you're talking about a tile or something else there.

Sorry about that.
Thinset brand Crest. Porcelanato
This is the manufacturers site but the exact thinset isn't there.
It states in the package that it's for porcelain or low absorption tile.
I'm using ceramic 12x24.
I'm heading to Lowes/Home Depot. Versabond or Mapei.
Even though the guy said it was fine.... I'm not sold.

Thanks for all the help! This forum is amazing!

I know nothing about the product at all and I've never heard of the company. I do see the mortar on the link you posted, but it's not in English. Only think I could read was that it exceeds ANSI A118.4 and would, technically, be a suitable product for your application.

Use it if you wanna. Not likely to find many comments here on our forums about it. I found one reference from 2009 from one of our Canuck members saying the company had been bought out by Custom Building Products.

If you're got access to VersaBond, I'd favor that over an unknown product.

My opinion; worth price charged.

Thanks! I agree.

Crest is ANSI certified and Has the Older TCNA certification....That said, Mapei products ( example Ultraflex II ) or Laticrete's 253 gold, OR of course Custom's Versabond are well known and well respected products..

and Has the Older TCNA certification....When did the TCNA start certifying products, Todd?

Here are some photos from my ongoing bath remodel.

I plan on installing a 'barn door' over the main entrance of the bath area, since I demo'd the door to the toilet/shower area and modified the wall into a pony wall.

I've used the Goof-Proof shower system (seemed like a good idea at the time).
I will spend the extra and go for the Schluter/Kerdi system.

I'm laying out the tiles now...

The galvanized plumbing was literally disgusting. I replaced these lines back to the header with PEX.

The pour was not as pretty as I had hoped for but... I think it will do.

I've done a complete kitchen including counter tops and walls as well as enclosed the window ledges, etc... I took my time and was creative with the patterns. I've done a couple of bathroom lavatories and replaced a couple of rows tile with a tub replacement from steel to cast iron.
This will be my first full wall with large tiles. I'm really antsy about it...
I picked up -
instead of using the Crest Porcelanato that I bought with the tiles.
but I noticed that it is "polymer enriched".

I flip-flop on the mortar from "everything's going to be fine" to "OMG I'm totally screwing up".... :laugh2:

That thinset mortar will be fine for your applications.

My opinion; worth price charged.

finding time for a bucket of thinset between life and work and other projects that seem to crop up.....

My cut around my niche was just too off and I pulled those two tiles off. Wow - If those two are indicative of how those tiles are secured - I'm all good.

Four hours later - I chiseled and scraped and bled and swore a couple of times. I cleaned it all and have completely repainted with RedGard.

In the process, I nicked one of the adjacent tiles pretty good. They are ceramic tiles and my nice gray/white tiles, now has a 1/4" x 1/2" brown/red gash.

My question: Is there any such "touch up paint"? An off grayish touch up would be better than the red clay look!

Thanks for any help!

I'm very happy with the detail that I went through to make this a 100% solid installation! Far from perfect but we love the improvement.
I did every single piece of work myself - teardown to studs and complete rebuild, including the cabinetry.
I got so much helpful information from this site - I'm very appreciative!
